Sexy (And Sloppy) In The City: Best And Worst Monday

Sarah Jessica Parker had a style hit and miss over the weekend, stepping out in sexy and sloppy threads!  The fabulous fashionista attended the Tribeca Film Festival premiere of Ultrasuede: In Search of Halston, shimmering in silver ensemble from the Stella McCartney Spring 2009 Collection, however, on a daytime outing with her babies, the usually a la mode mom looked super disheveled, wearing an oversized v-neck t-shirt, with a frumpy skirt and white tennis shoes.

Rihanna looked glam glam glam in Paris, pairing a stylized Burberry Prorsum trench with Balmain booties, while the Material Girl awkwardly paired embellished sandals with an athletic tracksuit in NYC!  Suddenly single Halle Berry looked casually chic, wearing an oversized Riller & Fount top with leggings, grommeted sandals and Ralph Lauren shades, as did Kate Bosworth, who rocked uber-short J Brand cutoffs with a white blouse.
